Hi All, I am trying to configure Portal from FME Forms and having this issue. I followed instructions from this earlier post. Failing to connect to Esri ARCGIS Portal | Community. While testing Web Connection in FME Forms, I get this error. I am not sure what is causing this error?
Appreciate any input.
Thanks

Hi @sunnywaygis Can you verify that your ArcGIS Enterprise/Portal is configured to use SAML authentication? You can verify this information from your GIS Administrator
or you can simply check in your ArcGIS Enterprise by browsing to this location Organization → Settings → Security → Logins
Since the error is 401 Unauthorized .. It is prudent to ask if the USER trying to access the Portal have permission to connect using OAuth or not.
From Esri documentation: Exception representing a 401 - Unauthorized response HTTP error. This HTTP error occurs when a network request is made to a NTLM-secured service, with no or invalid username/password.
Can you review some Log files from ArcGIS Enterprise to check if there is any useful information?
Thanks Rahul for your reply. We use IWA for authentication within our Portal. I also checked Portal logs, don't see specific error for user in portal logs. I am able to login to Portal site without any issues. Does it have to SAML authentication for FME Form to connect to Portal?
Appreciate any feedback.
Thanks
Hi @sunnywaygis To use Web Services, OAuth currently only support ArcGIS Build-in or SAML authentication.
If you have your portal configured with IWA (web authentication), you can access the service by setting the authentication to either Kerberos or NTLM
Thanks Rahul, I was able to connect to services using NTLM method on the reader. I really appreciate your help.
